Frequently Asked Questions

Will merged PDFs lose their format?

No. The merging operation sequentially stitches the pages exactly as they are without modifying the text, image, or layout formats of the individual files.

Are encrypted PDFs supported?

Currently, password-protected PDF files are not supported. Please decrypt them before attempting to merge.

What's the maximum number of files I can merge?

There is no fixed limit. Since all processing runs locally in your browser, the maximum capacity mainly depends on your device's available memory.
